Senior Infrastructure Engineer

Required Qualifications, Capabilities, and Skills

· 5+ years of hands-on experience in infrastructure engineering with demonstrated depth and breadth of knowledge across multiple domains (virtualization, storage, networking, Windows Server administration).

· Strong expertise in Microsoft Hyper-V at enterprise scale: failover clustering, live migration, storage spaces / S2D, virtual networking (Hyper-V virtual switch, SET), and Windows Server administration.

· Strong proficiency in PowerShell scripting for infrastructure automation, host configuration management, WMI-based inventory collection, and operational tooling.

· Demonstrated ability to audit performance of complex infrastructure architecture across the full stack and to maintain architecture artifacts (design documents, decision records, diagrams).

· Experience with storage performance analysis and optimization in virtualized environments — benchmarking, capacity planning, and storage policy design.

· Ability to evaluate hardware BOMs for Hyper-V suitability — assessing processor/memory ratios, storage I/O characteristics, network throughput, and overcommit profiles.

· Experience with infrastructure automation and configuration management tools (DSC, SCCM, Ansible, or equivalent) at data center scale.

· Experience advocating for and implementing infrastructure automation — CI/CD pipelines, operational process improvement, and configuration-as-code — with a focus on scalability versus resource use.

· Track record of providing stewardship to other engineers through technical guidance, design review, and documentation.

· Degree in Computer Science, Computer Engineering, Information Systems, or a related technical field.

Preferred Qualifications, Capabilities, and Skills

· Experience with Windows Server Failover Clustering (WSFC) and Storage Spaces Direct (S2D) at enterprise scale.

· Experience with additional hypervisors (VMware ESXi, KVM, etc.) — production experience with dual-hypervisor environments are a plus.

· Familiarity with server hardware architecture (Intel Xeon, AMD EPYC, NVMe storage, GPU accelerators) sufficient to evaluate hardware proposals for Hyper-V workload suitability.

· Experience with network fabric integration in virtualized environments — VLAN, SDN, load balancing, and network adapter teaming.

· Working knowledge of C# / .NET for maintaining and extending infrastructure automation platforms.

· Experience with Microsoft System Center (VMM, SCOM, SCCM) at enterprise scale.

· Experience with security compliance remediation — Qualys vulnerability management, break management, and security baseline enforcement.

· Experience with performance testing frameworks (elbencho, VMFleet, diskspd, fio or similar) for storage and compute validation.

· Familiarity with using generative AI tools to accelerate engineering and research cycles.

Job Responsibilities

Architecture & Systems Design

· Design and maintain Hyper-V cluster architectures including failover clustering, live migration, storage configuration, and network topology across global data center pools.

· Evaluate hardware BOMs proposed by hardware engineering for Hyper-V performance characteristics — processor/memory ratios, storage throughput, network bandwidth, and overcommit suitability — and provide technical feedback to inform procurement decisions.

· Audit performance of complex virtual infrastructure across the full stack — compute, storage, networking, and hypervisor layers — and maintain architecture artifacts (high-level design documents, decision records, diagrams) using firmwide tooling.

· Develop and document reference architectures and best practices for Hyper-V cluster deployment, storage configuration, and workload placement.

Coding

· Create and maintain automation for virtual infrastructure lifecycle management — provisioning, configuration, patching, compliance enforcement, and decommissioning of Hyper-V workloads — using PowerShell, WMI, and the team's .NET-based workload management platform.

· Write PowerShell scripts for host configuration management, inventory collection, cluster operations, and firmware deployment across the Hyper-V fleet.

· Maintain and extend the existing C# / .NET 8 workload management platform as needed — including the server-side orchestration API, distributed worker engine, and Windows client agent components.

· Provide stewardship to other engineers in support of quality delivery — peer reviewing automation scripts, infrastructure designs, and technical documentation.

Automation & Continuous Delivery

· Advocate for and implement infrastructure automation, identifying opportunities to automate, combine, or simplify operational processes with a focus on scalability versus resource use.

· Develop and maintain automation for Hyper-V host configuration, cluster provisioning, rolling upgrades, and compliance enforcement using PowerShell DSC, scripts, and the team's workload management platform.

· Support and evolve CI/CD pipelines for infrastructure automation tooling, including multi-environment deployment and automated testing.

Distributed Systems Design & Development

· Plan and execute Hyper-V cluster upgrades, Windows Server rolling upgrades, and hypervisor patch rollouts across production environments with zero or minimal downtime.

· Troubleshoot production issues across the virtual infrastructure stack — hypervisor, clustering, storage, and networking layers — using structured logging, event tracing, performance counters, and vendor diagnostic tools.

· Consider all risks, potential environmental impacts, and FinOps implications when designing and implementing infrastructure changes.

Data Fluency

· Identify appropriate data sources and apply appropriate methodologies when making data-based recommendations for capacity planning, performance optimization, and hardware procurement decisions.

· Conduct storage and compute performance benchmarking using industry and internal tooling (e.g., elbencho, VMFleet, diskspd) to validate hardware configurations and inform deployment decisions.

· Deliver against defined SLOs and SLAs; track and reduce events leading to errors or risks.

Cross-Functional

· Collaborate with hardware engineering on server platform evaluation, providing Hyper-V-specific performance requirements and validation feedback.

· Collaborate with vendor partners (Microsoft) on Hyper-V roadmap alignment, feature adoption, and escalation support.

· Collaborate effectively across infrastructure engineering, operations, security, and capacity planning teams.

· Leverage AI-assisted tooling for research, prototyping, and automation development to accelerate engineering cycles.

· Contribute to team and organizational goals.
